My budget is a shoestring right now. I'm talking to AT&T about getting a cheaper wireless plan and move from a USB cell stick to a portable hotspot, but I don't have the money for a new device and activation fees just yet.

After all, I don't use Linux and FOSS everything, just for ideological reasons. The low sale price helps.

Edit: Just so we're all on the same page, my "must have" features are a memory card slot and bluetooth.
